Default Door Removal & "Wiring"

I'm changing the drivers door out with one from an L100 with no power mirrors. Is there any sure-shot method to removing the wires from the L100 door to the L200 ? I cut the wires from the L100 at the yard for a quick way to remove it. Since mine has P.M. and the 100 doesn't, I'm going to have to remove the wiring from both doors and run my wiring thru for the correct wiring to work the mirrors. It appears removing the outside door skin may be easiest to get access to them. In other words, some modifications may be needed to make this work. I would assume, like other brands that there should be a plug under the left side to unplug to remove the door. That would be the sensible way to design it.Thanks in advance.

Default Re: Door Removal & "Wiring"

Much of your L200's wiring harness is attached to the inside steel panel and some of that wiring travels through to the interior trim panel for the door lock and mirror switches (and courtesy door light if so equipped). Carefully observe the routing of the harness on that door - take pictures - and mark up the attachment points onto the L100 door. There's nothing unusual about removing a wiring harness, but certainly no "sure-shot" method either. I believe that there's enough room between the interior panel and the door skin so that it's not necessary to remove the door skin to access the wiring harness for either removal or installation, but you'll know after you've examined things. (FWIW, I replaced my left rear door wiring harness without removing the door skin.)

If you must fully remove the outer door skin then the outside handle must be removed first. Be sure to pick up a small trim removal tool to separate the plastic pins from the outer door handle and remove the handle. The common trim panel removal tool is too large to work on that part (this I know from experience). I could be wrong, but I suspect that the door's wiring harness connector goes to the front pillar and inside of the black loom because that's how it's set up for the rear doors where the connector goes to the center pillar.

What has me more curious about your situation is what you intend to do with the power door lock and the power window. An L100 didn't have those as stock items, but your L200 does. Are you transferring the power door lock components and the window regulator along with its motor as well? Your power door lock switch at the driver's door is utilized to program an automatic locking/unlocking feature so without it that feature is negated. (I use it and am glad to have it. It seems to me that there may be one other item which that switch helps to activate, but I can't recall it presently.) I don't know what effect, if any, the lack of a power window there will have on the rest of that system.

Maybe I'm not understanding something but I would think you can reuse the existing wiring harness and PM by reusing the interior door panel. The only thing different will be the metal door and possibly the plastic exterior panel.

I think you may be overcomplicating this job for yourself.

If all you are doing is equipping your car with power door mirrors, then that is all you should focus on. It doesn't require a wholesale changing of doors or door panels.

The Saturn wiring loom is as far as I have found a standard wiring loom that incorporates all the various wiring for what were optional extras such as power/heated seats, fog lamps, etc. The wiring is there. You just need the components and any trim relative to that fitting. The mirrors outwardly and the trim sail panels are the same whether powered or not.

What you should have done at the JY instead of hacking at a wiring loom is trace it back to where it connected and then just unplugged it. If you had done that the retro fit would have been easier What I would suggest you do now is remove the interior door panel OR the outer door panel and compare the wiring on each of the looms you have. That will tell you if they are both the same. if they are, that makes your job much easier.

Just disassemble your front door and disconnect the harness from everything.
You are correct that most cars have a disconnect so that you can unplug and remove the door with the harness attached.
There is a plug on the rear doors.
There is not a plug on the front doors.
